Problems solved by technology
[0006] This measuring system cannot be removed from the device without major structural changes
Therefore, such a non-modular system in particular does not offer the possibility of retrofitting an existing fryer with a measurement function as described at the outset without a permanently installed sensor at low cost
With existing systems, such retrofitting is complex and expensive, and simultaneous or flexible monitoring of several tanks is not possible in existing systems

Embodiment Construction
[0055] figure 1 A device 18 typical for the prior art is shown, which has a screen with an input unit 22 and a tank 19 filled with oil, wherein a circuit is formed via lines 12, 13 for extracting and delivering oil and a pump 5, said The loop circulates the oil from the tank 19 through the filter 15 and back into the tank 19 . As indicated by the dotted frame, sensors are typically fixedly installed at one or more points in the circuit or in the oil sump 19 for monitoring the oil. In the case of existing oil sumps with pump 5 for circulating the oil, this means that such a sensor system can only be retrofitted via major modifications to the oil sump 19 and the associated piping system.
[0056] figure 2 It is shown how the oil measuring device 1 according to the invention can be used for monitoring an existing oil sump 19 . For this, according to the invention it is only necessary to introduce the probe 2 into the oil, so that the oil is taken out of the tank via the inlet 3...

For the monitoring of an oil situated in a tank 19, it is provided that an oil measurement device 1 be equipped with a rigid or flexible probe 2 such that, by the use of a pump 5 integrated in the oilmeasurement device 1, oil can be delivered out of the tank 19 via an inlet opening 3 at the proximal end of the probe 2 into a measurement chamber 4, which is connected to the probe, of the oil measurement device 1. Here, the oil measurement device 1 has a measurement sensor for determining the quality of oil situated in the measurement chamber 4, and the pump 5, in conjunction with the probe 2,is configured such that oil can be returned from the measurement chamber 4 to the inlet opening 3 and thus to the tank 19.
Description
technical field [0001] The invention relates to an oil measuring device for determining and / or monitoring the temperature and / or quality of oil located in a tank. [0002] The invention also relates to a method for monitoring oil located in a tank. In this case, depending on the application, different parameters for monitoring may be of interest, such as the temperature and quality of the oil or eg the number and / or duration of heating cycles the oil is subjected to in use. Background technique [0003] In the prior art, for example, there can be a large number of household and / or catering appliances which have tanks, in particular electrically heatable tanks, which are filled with liquefied oil or grease during operation. Especially in large kitchens, for example, stationary fryers are used for which, for reasons of food hygiene, the temperature of the liquefied oil or fat needs to be monitored, preferably continuously, and the quality of the oil or fat needs to be measure...
